ADOLPH OLSON, OF BUTLER, MISSOURI.

PLOW.

SPECIFICATION forming part of Letters Patent No. 378,900, dated March 6,1888.

Application filed November 22, 1887. Serial No. 255,852. (No model.)

To aZZ whom it may concern.-

I at Butler, in the county of Bates and State of Missouri, have inventedcertain new and useful Improvements in Plows, of which the following isa specification, reference being bad therein to the accompanyingdrawings.

This invention pertains tocertain new and useful improvements in plows,having for its object the provision of simple and efficient means forcausing the plow-point to be always properly presented for operation.

To this endthe invention consists, briefly, in the application to thelandside of a bar or arm pivoted at one end and capable of adjustment,substantially as hereinafter fully set forth, and particularly pointedout in the claim.

In the accompanying drawings, Figures 1 and 2 are opposite side views ofa landside, showing my invention as applied thereto. Fig. 3 is a detailperspective View, and Fig. 4. isa cross-sectional view.

Referring to the drawings, A represents the ordinary landside, having aportion ofits lower edge and inner surface removed, forming recesses aa. On the inner surface of this landside is formed a thickened orwidened portion, a, through which is formed a vertical opening oraperture, 0. and in an aperturein the side of this widened portion aworks a set-screw, a as shown.

B is an adjustable bar or arm, provided on its upper surface with anapproximately L,- shaped groove, 1), extending to near the for- Ward endof said bar or arm. This bar or arm is pivoted at its forward end in theforward end of the groove a, and said bar, being made to conform to thegrooved surfaces of thelandside, fits snugly in position therein. Tothis bar or arm B is rigidly secured a vertical rod or short bar, b,projecting through the aperture or opening in the widened portion a ofthe landside, said rod or short bar being engaged and held in thedesired position by means of the set-screw a It is well known that inpractice the heel of the landside becomes worn, consequent upon frequentusage, thus causing the plow to run unevenly. This objection myinvention is designed to obviate by reason of the employment of the armor bar, which upon becoming worn on its under surface can be lowered tothe desired extent and securely retained in position by means of theset-screw bearing against one side'thereof. I

From what has been said it will be seen that my invention is extremelysimple and cheap, and that by means thereof the plowing is alwaysperformed in the desired manner, and the necessity of replacing the wornlandside with anew one, when worn,is avoided,

thus proving a great saving in this respect.

I claim as myinvention- The combination, with the landside havinggrooved surfaces, of the bar or arm having an upper groove correspondingto that of said landside, and pivoted at its forward end, and the rod orshort bar passed through a thickened or widened portion and held by asetscrew, substantially as shown and described.

In testimony whereof I affix my signature,in presence of two witnesses.

ADOLPH OLSON.
